AI Technical Summary

Benefits of technology

The present invention is about a plasma cutting torch that has a special design. The torch has an insulating part and a main part. This design makes the torch's leads shorter, which helps to handle higher levels of electric current. This "technical effect" makes the torch more efficient and effective for cutting through materials.

Problems solved by technology

Therefore, the more complex the movement and control of the torch the more often the operation will have to be stopped to unwind the torch.
This increases downtime of the cutting operation and can lead to premature failure of the torch connections through constant loading and unloading of torsional stresses.

Embodiment Construction

[0014]Exemplary embodiments of the invention will now be described below by reference to the attached Figures. The described exemplary embodiments are intended to assist the understanding of the invention, and are not intended to limit the scope of the invention in any way. Like reference numerals refer to like elements throughout.

[0015]FIG. 1 depicts an exemplary robotic system 10 using a torch 200 in accordance with an exemplary embodiment of the present invention. It is noted that for purposes of the following discussion, the system will be discussed as a plasma arc cutting system. However, exemplary embodiments are not limited to being used in arc cutting systems. Embodiments of the present invention can be used with many systems which require complex movement of a torch like assembly, in which rotational movement and forces are imparted. For example, embodiments of the present invention can be used with arc welding, electroslag welding, cladding, joining, hot wire and additive ...

Abstract

A plasma torch assembly is provided with a torch body having a primary portion and a dielectric portion. The use of the dielectric portion allows for the length of the leads in the torch body to be shorter than known torches, especially in higher current applications. This provides for added stability and longevity of the torch and its components.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]Systems and methods of the present invention relate to plasma cutting, and more specifically to arc plasma cutting using a torch assembly that can be mounted in robotic arm systems.[0003]2. Description of the Related Art[0004]The use of plasma cutting systems in various industries has grown, including the use of plasma cutting systems with robotic systems. In such applications, the plasma cutting torch is secured to a robotic arm or motion mechanism which moves the torch in many different directions. In fact, in many robotic applications the robot has many different axis of movement. This complex movement often requires the torch to move relative to the robot arm which imparts a rotational movement. Because of the electrical and cooling liquid connections on the torch this rotational movement must be limited so as to not break these connections. Further, after a certain amount of movement the operation must be stopped s...
